The center pin was not tight enough probably, I am always amazed at how tight is has to be and doesn't snap in two during the tightening process. Be aware of coarse that it can break.Okay, big update. In my frustration and thinking it might be the unit itself, I tried building on another Ithaka clone from another vendor. Same problem. It came assembled but the center pin was not tight, so I tightened it. When I screwed down the ceramic housing assembly on to the feeding system, the center pin was still tight. I then screwed down the feeding system tightly into the base, then screwed down the ceramic housing assembly until it was tight. When I screwed it into the 510 adapter, put it on my mod and tested it, I got the same short. I unscrewed the ceramic housing assembly and the feeding system. I automatically noticed that the center pin was loose again. Is this possibly what is causing the problem? I know how well the Ithaka can perform when it's working, and through hell or high water, I'm going to figure this thing out.
Every Oddy/clone, Ithaka/clone that I've seen so far have been shipped either loose or almost loose. Even after initial tightening that I find them loose again when doing the next build so I tighten it a little more than the time before, eventually it stays tight. Once tight there is not much reason to ever disassemble again unless to replace the ceramic.
Also when assembling the basic feeder ring and ceramic housing assembly to the base position the basic feeder ring on the housing so that the bottom is even with the bottom of the o-ring on the ceramic housing. Position the basic feeder ring where that you want it, probably screwed all the way down, then screw the ceramic housing assemble down tight enough to compress the o-ring and tight enough that adjusting the mouthpiece won't cause it to back out. Be sure to lube the o-ring with juice or a tiny amount of Vaseline, I use juice. This is how I do this stuff, others may have other methods.
